I have a loop that I am trying to put key values pairs into a hash
from. There are 6 rows of data,
when I do a outputHash.inspect all I get is the last value. Where do
the other values go or what I am I doing wrong?
row.each {|line|
line =~ /^\s*\d+\s*\S+\s*\S+\s*(\d+)\s*\D+(\d+)/
port_num = $1
if $1
status = $2 =~ /0/ ? "Available" : "Not Available"
outputHash = {port_num => status}
}
outputHash.inspect

You want outputHash[port_num]=status (and the variable needs to exist before the block (becaused of scoping) Fred> >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
